Hydrostatic pressure test
Pressure test before attaching gas piping or electrical supply.
1. Plug any necessary boiler tappings or openings.
2. Do not use gauge supplied with boiler for pressure testing.
Install gauge with appropriate range.
3. Fill boiler with water. Vent all air. Test steam boilers between
45 - 55 psi. Test water boilers at 1-1/2 times maximum work-
ing pressure.
Do not leave boiler unattended. A cold water fill could
expand and cause excessive pressure, resulting in severe
personal injury, death or substantial property damage.
4. Verify gauge pressure is maintained. Check for leaks. Repair
if found.
Leaks must be repaired at once. Failure to do so can
cause boiler damage, resulting in substantial property
damage.
Do not use petroleum-based sealing compounds in
boiler system. Severe damage to boiler will result,
causing substantial property damage.
5. Drain boiler and repair leaks if found.
6. Retest boiler after repairing leaks.
7. Remove plugs from any tappings that will be used for controls
and accessories. Refer to Table 4 and Figure 5.
